Is jar creation necessary to execute MR on a remote cluster

由 北战南征 提交于 2020-01-14 03:35:07
问题 I have been trying Spring Data for Hadoop to execute a MR job from my local Windows STS on a remote Hadoop cluster. The issue I face is mentioned in detail here There's a similar thread that has forced me to ask the below question. Is it necessary to first create a .jar file on my local windows machine(within the Eclipse/STS project's lib etc.) before it can be executed on a remote Hadoop cluster? Can't Spring Data simply push my code onto the remote cluster and trigger the execution? 来源：

问题 i'm trying to pass command line arguments in my Spring Boot Yarn application and am having difficulties. i understand that i can set these in the yml document spring.yarn.appmaster.launchcontext.arguments but how can it from the command line? like java -jar MyYarnApp.jar {arg0} {arg1} and get access to it from my @YarnContainer ? i've discovered that @YarnProperties maps to spring.yarn.appmaster.launchcontext.arguments but i want to set them from the command line, not in the yml 回答1: You are

How to submit multiple Spark applications in parallel without spawning separate JVMs?

由 有些话、适合烂在心里 提交于 2019-12-10 06:41:19
问题 The problem is that you need to launch separate JVM to create separate session with different number of RAM per job. How to submit few Spark applications simultaneously without manually spawning separate JVMs? My app is run on single server, within single JVM. That appears a problem with Spark session per JVM paradigm. Spark paradigm says: 1 JVM => 1 app => 1 session => 1 context => 1 RAM/executors/cores config I'd like to have different configurations per Spark application without launching

Triggering spark jobs with REST

由 馋奶兔 提交于 2019-11-28 04:43:31
I have been of late trying out apache spark . My question is more specific to trigger spark jobs. Here I had posted question on understanding spark jobs. After getting dirty on jobs I moved on to my requirement. I have a REST end point where I expose API to trigger Jobs, I have used Spring4.0 for Rest Implementation. Now going ahead I thought of implementing Jobs as Service in Spring where I would submit Job programmatically, meaning when the endpoint is triggered, with given parameters I would trigger the job. I have now few design options. Similar to the below written job, I need to maintain
